STEAM- GENERATOR ATTACHMENT TO STEAM-BOILERS.'

SPECIFICATION forming part of Letters Patent No. 305,803, datedSeptember 30, 1884.

Application filed January 16, 1884. (No model.)

To @ZZ whom it may concern,.-

Be it known that I, Baxrnn DAvIs, of Defiance, in the county of Defianceand State of Ohio, have invented new and useful Improvements inSteam-Generator Attachments; and I do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings, which form a part of this specification.`

This invention relates to certain new and useful improvements insteam-generators designed to be used either as an attachment to asteam-boiler or detached therefrom.

The object of the invention is to provide a I 5 small steam-generator bymeans of which the water entering at one point is compelled to travel bya very 'circuitous route to the point of exit, so that alarge surface ofsuch water is brought into contact with heated surfaces, 2o which willrapidly convert such water into steam.

The device is especially adapted to be attached to steam-boilers usedfor providing steam for engines, and when so attached the heat of asingle lamp applied to the under surface of this attachment will tend tokeep the Water in the boiler very hot, even when the res are withdrawnfrom the furnace, as is usually done at night, so that upon kindling 3othe fires in the morning it will take but a few moments and a smallexpenditure of fuel to get up steam for operating purposes.

The invention consists in the peculiar construction and operation of thegenerator, as,

more fully hereinafter described.

Figure l is a plan view with the cover removed. Fig. 2 is a plan of thecover. Fig. 3 is a vertical central horizontal section showing theoperation under a lamp-flame or gasoline-burner.

`In the accompanying drawings, which form a part of this specification,A represents a shallow case with the top removed and the bottom castintegral with the body, the depth of the latter being but one and aquarter inch, or thereahout. This body is divided by means of partitionsB, cast, preferably, integral with the bottom and sides, and alternatelyextending from one side nearly to the 59 other, so that water enteringat C must travel a long distance around the ends of these partitions tofind an outlet` at D, the inlet and outlet, for instance, being bothconnected with ciency of service.

a steam-boiler. The cap ,or top plate, E, is provided with lugs a, andsimilar lugs-b, upon the body, provide means, with suitable boltspassing through saidlugs, of securing the cover or cap in place, agasket not being necessary if the parts are properly fitted together.

This device will be found peculiarly applicable to steam fire-enginesfor the purpose of keeping up steam in the boilers when off duty; or thegenerator may be placed on astove and suitably connected for the purposeof heating the Water circulating through the same for bath-room orculinarypurposes. In the use of this generator' the principle of thebuoyancy of heated water is utilized, the generator when in use asattached to boilers being placed at the lower extremities thereof, whenthe cold water, entering its inlet from the boiler, will be heated inits passage through the device, and returned to the boiler by theincreased buoyancy given to the water by the heat through theoutlet-pipe.

I am aware that various devices, most of them being of an expensivecharacter, are used for a like purpose, employing the same principle ofoperation; but I am not aware ot' any device for this purposeconstructed like mine, and which can be furnished to the public at so4small an expense, and requiring so small an amount of. fuel and labor,and giving such efii- V What I claim as mv invention isl. A steam-boilerattachment consisting of a shallow' chamber within which is provided acircuitous passage from the water-inlet to the water-outlet, and whichis also provided with a removable cover or top plate, substantially asand for the purposes described.

2. The steam-generator attachment herein described, consisting of theshallow chamber A, having partitions B cast integral with the bottom andsides, and alternately extending from one side nearly to the other, saidchamber being provided with inlet C, and outlet D, and lugs b, andremovable cover E, having lugs a, substantially as and for the pur- 1o(poses spe/ciicd.
